Is this safe to enable?

On my xubuntu-22.04 /proc/sys/kernel/unprivileged_userns_clone=1,
/proc/sys/user/max_user_namespaces=63222. I don't know how much requires Steam, but I think you can increase this value.

Today Steam worked again, so I guess the issue solved itself. Maybe some app temporarily used too many namespaces?
